I use it for everything. My notebooks look something like this Receipts (fwd via email receipts/tickets/confirmations), GTD (todos, to read, to buy, etc.), Code (html/js/css/code articles), Pulse News (my Pulse saved stories http://pulse.me), Work (all work related notes), Design (pretty images, design, icons).

New fullscreen mode on OSX makes evernote a joy to use.

Hope this helps!
